I like the idea of draining the patch queue mid-way through the release 
cycle. That'll hopefully encourage people to submit patches earlier in 
the release cycle, knowing they will be reviewed. It'll also give people 
working on external projects, drivers and tools, a checkpoint to sync with.

But I don't like the idea of making a release out of it. Who would use 
such a release? No one in production. Making a release comes with a 
cost, even if it's just a dev release.

One could also argue that we don't need the mid-cycle checkpoint, if we 
just keep the patch queue empty all the time. In the end, it comes down 
to how many people we have actively reviewing patches and giving 
feedback (I agree that it's not a linear relationship as you pointed out 
later in your mail, though). I believe a mid-cycle checkpoint would help 
by directing efforts to review, just like the pre-release feature freeze 
does.

I have no reason to believe that the next release will have less patches 
in it, so if we went down that path we could never release a stable 
release. If we have reasonable doubts about the stability of a patch, it 
should not be included. That said, all patches come with a risk.

We're having a short 8.3 cycle because we wanted to shift our release 
schedule from Autumn to Spring. That would get us back to releasing in 
Autumn.
